Politically:
Labour to win a thin majority in a midsummer General Election, on a nevertheless large swing. Sunak to be replaced as Tory leader by Mordaunt. An improved showing by the Lib Dems and a poor result for the SNP.
Biden to withdraw from the presidential race, with Gavin Newsom becoming the Democrat nominee. He beats Trump in a landslide, but Trump behaves exactly the same as in 2020, with similar results. By the end of the year, Trump has been found guilty in at least one of his criminal cases and receives a prison sentence.
That may be wishful thinking. If Biden runs, I predict a result similar to 2016. Trump wins, before embarking on a crusade of politically-motivated prosecutions. The bright economic future Americans predict will happen under Trump (sigh) fails to occur, and growing public tension leads to a split in the Republican Party, with protests and riots, and Trump's reaction to them, forcing the impeachment of Trump within months. This also engulfs his vice president, causing a political crisis.
(OK I think I've gone slightly into 2025 with that, sorry!)
